Sunbrella fabric is a fantastic investment for your outdoor space. It's engineered to resist fading, water, and stains. But even the most durable performance fabric needs regular care. Over time, pollen, bird droppings, food spills, and environmental grime can build up, leaving your cushions looking tired and dull.
The good news? Restoring them to their original vibrancy is a straightforward process that doesn't require expensive products or professional services. With a little know-how and a regular routine, you can keep your outdoor furniture looking like new for many seasons. For more on this, see our guide on how to clean sunbrella outdoor furniture cushions.
This guide walks you through everything from simple weekly upkeep to deep cleaning stubborn stains and safely dealing with mildew, so you can spend less time scrubbing and more time enjoying your patio.
Before You Begin: What You'll Need
Gathering your supplies before you start makes the job faster and more efficient. For most tasks, you'll need:
- A soft-bristled brush (a scrub brush with synthetic bristles, or a grout brush for stubborn areas)
- A clean sponge or soft cloth
- A garden hose with a spray nozzle
- A bucket
- Mild liquid soap (like Dawn dish soap) or a specialized Sunbrella cleaner
- Optional: a vacuum with a brush attachment
Avoid using chlorine bleach, harsh solvents, or dry-cleaning chemicals. These can damage the fabric's water repellency and its vibrant color. For more persistent issues like mold, you can work with a diluted bleach solution, but it should be a last resort, which we'll cover below.

Preparation: Setting Yourself Up for Success
Proper preparation is the foundation of a thorough clean. It prevents surface grit from grinding into the fabric fibers and ensures your chosen cleaner works effectively.
Clear the Area and Protect Your Space
Move your cushions to a clean, flat surface, like a driveway or patio. If you're cleaning near your lawn or garden, sweep the area first. This prevents freshly cleaned cushions from picking up grass clippings or dirt.
Remove Loose Dirt and Debris
The most critical first step is to remove all loose particles. Use your soft-bristled brush to gently sweep the entire surface of the cushion, paying extra attention to creases, seams, and the corners where dirt and crumbs tend to gather. A vacuum with a brush attachment is an excellent alternative, especially for the underside of cushions.
Check Care Instructions and Remove Covers
Before you get your cushions wet, check the care label. While Sunbrella fabric is consistent, the construction of your cushion (e.g., sewn-in foam vs. a removable cover) might influence your method.
- For removable covers: Unzip and remove them. The foam core should be cleaned separately and allowed to dry completely.
- For sewn-in cushions: You'll clean the entire cushion, but be careful not to soak the foam core, as it can hold water and mold, leading to a lingering damp odor. A common mistake is saturating the cushion, which can ruin the foam.
Choosing the Right Cleaning Solution
The market is full of cleaning products, but you don't need many. For Sunbrella, you need a solution that's effective yet gentle enough to protect the fabric's water and UV-resistant properties.
The Trusted Mild Soap and Water Mix
For about 90% of cleaning jobs—including regular upkeep and light soil—a simple solution of mild soap and water is all you need. This is your go-to, everyday cleaner.
- The ratio: Mix one tablespoon of mild dish soap (like Dawn) with one gallon of warm water.
- The method: Dip your soft brush into the solution, gently scrub the fabric in a circular motion, and allow the soap to sit for a few minutes to break down dirt.
- The key: Rinse thoroughly to ensure all soap residue is gone, or it can attract more dirt and potentially dull the fabric's color.
Specialized Sunbrella Cleaners for Stubborn Grime
When your cushions face wind-blown grime, ground-in dirt, or other stubborn staining, a specialized cleaner designed for acrylic fabrics can be more effective. Products like Sunbrella's own 303® Fabric Cleaner or Mary Ellen's Mildew Stain Remover are specifically formulated to tackle deep cleaning without compromising the fabric's performance.
- How to use: Always following the manufacturer's instructions, apply the cleaner to the fabric, scrub gently, allow it to sit, and then rinse thoroughly.
- When to use: These are ideal for biannual deep cleans or when the mild soap and water mix isn't cutting it. You can also use a diluted household bleach solution (see below) safely if needed.
Step-by-Step: How to Clean Sunbrella Outdoor Cushions
Here is the core process for cleaning your cushions, from spot treatment to a full wash.
Step 1: Spot Clean Stains Immediately
The moment you notice a spill, tackle it. Catching a stain fresh is always easier than fighting an old, set-in one.
- Act quickly to blot up liquids with a clean, white cloth. Avoid rubbing, as this can push the stain deeper into the fibers.
- For a quick spot clean, mix a small amount of mild soap with warm water. Dip a cloth or soft sponge into the solution and dab the stain gently.
- Rinse the area with a clean, damp cloth and blot dry. Remember to treat the backing of the fabric too, as stains can wick through from the underside.
Step 2: Prep for a Full Wash
If the entire cushion needs cleaning, begin by brushing off all loose dirt and debris as described earlier. If you have removable covers, take them off. If the cushions are sewn-in, prepare the cleaning solution in a bucket.
Step 3: Wash the Entire Cushion
This involves cleaning the entire fabric surface, not just a spot.
- For removable covers: If your care label allows, you could hand-wash or machine-wash on a gentle cycle with cold water and a mild detergent. But hand-washing is the safest and most recommended method. Submerge the cover in the soapy water and gently squeeze the suds through the fabric.
- For in-place cushions: Using your soft brush, dip it into the soapy water and work up a lather over the entire cushion. Pay extra attention to heavily soiled areas, like where arms rest or where birds like to sit.
- Let it soak: Allow the soapy solution to sit on the fabric for 10 to 15 minutes. This dwell time helps the soap break down embedded dirt and grime without aggressive scrubbing. Scrub lightly in a circular motion, focusing on dirty areas without over-scrubbing, which can damage fibers.
Step 4: Rinse Thoroughly
This step is crucial. All the soapy water that you've worked into the fabric needs to be removed completely.
- Use a garden hose with a strong nozzle to spray down the entire cushion.
- Ensure you rinse away all the suds from both the surface and the underside, and check the seams where soap can hide.
- Leaving soap residue can leave a film that attracts future dirt and may cause the fabric to feel stiff.
Step 5: Drying Your Cushions Properly
The way you dry your cushions is just as important as how you clean them.
- Shake off excess water gently.
- The best method is to air dry them completely. Place the cushions upright or lean them against a wall in a shaded, well-ventilated area.
- Direct sunlight can cause fading, even with resilient fabrics like Sunbrella, so avoid drying them in the hot summer sun for extended periods. Drying in the shade avoids potential UV damage and protects the vibrant colors.
- Never put Sunbrella fabric in a clothes dryer or use a heater or iron on it, as the high heat can irreversibly warp or shrink the fabric.

Dealing with Mildew and Mold
While Sunbrella is manufactured to be resistant to mildew, it isn't immune. Mildew can grow if cushions are stored while damp or left in a consistently humid, leafy area. It lives and thrives on the fabric, feeding on dirt and other organic matter, feeding on the dirt embedded in the fabric, not the fabric itself.
The Safe Cleaning Solution for Mildew
For more stubborn mold or mildew, you can use a more powerful solution.
- The mix: Combine one cup of household bleach with one-quarter cup of mild soap in one gallon of lukewarm water. This is the most effective and safe route to remove mildew.
- The application: Using a soft brush, gently work the solution into the affected areas. Never soak the fabric completely, especially if it's a sewn-in cushion, to avoid soaking the foam core.
- Let it sit: Allow the solution to sit for up to 15 minutes. This dwell time is critical for the bleach to kill the mildew.
- The critical rinse: Rinse thoroughly with clean water, ensuring all suds and bleach are gone. It's imperative to air dry completely in a shaded area. Once dry, you may want to restore the water repellency of the fabric.
For persistent or heavy mildew growth, applying a cleaner with a pump sprayer can help ensure even coverage before you brush it in.
Restoring Water Repellency
It's important to understand that Sunbrella fabric is highly water-resistant, but it's not entirely waterproof. Over time, and after multiple cleanings, the protective finish can wear off. While Sunbrella remains durable and fade-resistant, you might notice that water no longer beads up as readily on the surface.
To restore this "beading" effect, you can apply a fabric protector. This is an optional but valuable step for maximizing the lifespan of your cushions.
- Choose the right product: Look for a water-based, fluorochemical protector designed for acrylic fabrics.
- Application: After your cushions are completely clean and dry, apply the product in a well-ventilated area, following the manufacturer's instructions—typically using a spray bottle.
- When to reapply: Depending on your climate and how often you clean, reapplication is generally needed every few months or after a deep cleaning.
Preventing Future Stains and Damage
Prevention is the best way to keep your cushions looking fabulous. Adopting a few simple habits can dramatically reduce the need for deep cleans.
Establish a Regular Cleaning Schedule
Consistency is key to maintaining a pristine outdoor space.
- Weekly: Do a quick 10-minute routine. Use a brush to knock off loose dirt, leaves, and pollen. This simple action prevents buildup.
- Monthly: Wipe down the cushions with a damp cloth. This is a quick way to remove light surface haze.
- Biannually: Do a deep clean using the full step-by-step washing process.
Keep Your Cushions Dry
The motto is: "Keep it dry." When not in use, especially after a rainstorm, stand cushions on their side to allow air to circulate.
- For storage, use breathable storage bags instead of plastic ones to prevent trapped moisture and mildew. A cool, dry storage location like a garden shed or garage is best.
- If you live in a humid environment, be extra vigilant about checking for damp spots and drying them quickly.
Use Protective Covers
Investing in high-quality patio furniture covers is an excellent way to shield your cushions from the elements when they're not in use. Covers protect against UV rays, sap, and heavy rain. Just ensure the cushions are completely dry before putting the covers on.

Frequently Asked Questions
Can I use a pressure washer on Sunbrella cushions?
It's not recommended. The high-pressure spray can force water into the foam core and can be too aggressive for the fabric weave, potentially damaging the fibers over time. A garden hose with a nozzle is powerful enough.
How do I get sunscreen or oil stains out of Sunbrella fabric?
Oils can be tricky. Start by blotting the area with a paper towel to remove excess oil. Then, apply a small amount of a grease-cutting dish soap (like Dawn) directly to the spot, work it in with a soft brush, and let it sit for 10 minutes. Rinse thoroughly with warm water. You may need to repeat the process.
Is it safe to use bleach on all Sunbrella colors?
While Sunbrella is solution-dyed, meaning the color is throughout the fiber, the manufacturer has guidelines. While a diluted bleach solution is generally safe on most Sunbrella fabrics, it's always best to test it in an inconspicuous area first, like under the seam, to ensure no color change occurs.
Why do my cushions smell after cleaning, and how do I fix it?
A musty smell almost always means there's trapped moisture. This can happen if the foam core got soaked or if the cushion wasn't dried completely. To fix it, ensure the cushion is dried thoroughly in the sun and fresh air. For sewn-in cushions, you can try standing them on their side to allow airflow. If the smell persists, the issue might be the foam core, which may need to be replaced. You can also sprinkle them with baking soda, let it sit, and vacuum it up. And for those whose sleep is affected by allergies, keeping outdoor fabrics dry contributes to a healthier environment overall.
